CORPORATION OF ILLINOIS PAPER ROLL AND GUARD THEREFOR Application filed July 17,

This invention relates to improvements in paper rolls and guards therefor and its purpose is to provide improved means for protecting the peripheral edges of paper rolls against injury. It is common practice to ship paper in large cylindrical rolls formed by winding a long strip of paper about the axis of the roll and the rolls thus formed are commonly protected by wrappings formed of. heavy paper or other flexible coverings. It frequently happens that the edges of these paper rolls are cut or have indentations formed therein during shipment with the result that a large number of superimposed layers of paper at the outer portion of the roll are damaged. These damaged layers of paper cannot be used by the consumer and result in a considerable loss, particularly in the shipment of the better grades of paper. The principal object of the present invention is to provide a metallic guard adapted to extend around each peripheral edge of a roll of paper to prevent injury thereto during storage or shipment. A further object of the invention is to provide an improved metallic guard having novel means for securing the ends thereof together when the guard has been applied to the paper roll. Still another object of the invention is to provide an improved guard for paper rolls comprising a pair of projecting tongues adapted to be overlapped and to be engaged by a stretching device preliminary to the application thereto of a sealing or other fastening means by which the overlapping ends of the guard are secured together. Other objects relate to various features of constructionand arrangement which will appear more fully hereinafter. Y

The nature of the invention will be understood from the following specification taken with the accompanying drawings, in which one embodiment is illustrated. In the draw mgs,

Fig. 6 is an enlarged plan view of the band illustrated in Fig. 4, showing the joint made by the metal seal at the overlapping ends thereof and V Fig. shows a. side elevation of the paper roll illustrated in Fig. 4, with the metal guard applied to both ends of the roll.

The improved guard of the present invention comprises a curved band 10 comprising a substantially cylindrical body portion 10 formed of sheet metal or the like and having an inwardly extending transversely corrugated flange formed integrally therewith. This band may be formed from a strip of sheet steel by bending one edge thereof transversely to form a flange and then providing the flange with a continuous series of transverse corrugations or the portion of the band which forms the flange may be corrugated prior to bending it inwardly. In the process of forming the band, it is passed through rolls to bend it into the annular form shown in Fig. 1. and the endportions of the band are arranged to overlap. The curvature of the band is such that its normal diameter is substantially the same as that of the roll of paper to which the band is to be applied with some allowance for contracting the band into tight engagement with the peripheral edge surface of the roll. The body portion 10 of the band is provided at one end with a iii) z: be)

longitudinal ,slit 10 forming a tongue 10 which is of lesser width than the body portion 10 and which extends for a consider able distance from the end of the band. The corrugated flange 10 preferably terminates adjacent to the end of the tongue 10 At the other end of the band 10, the corrugated flange 10" and a portion of the body portion 10 are cut away to leave a projecting tongue 10 which is of the same width as the tongue 10 and of at least equal length.

The band or guard thus formed is adapted to be applied to either peripheral edge of a roll 11 formed of a number of spiral convolutions of paper wrapped closely upon each other to form a cylindrical roll having a diameter substantially the same as, or preferably slightly greater than, the normal diameter of the guard 10, as illustrated in Fig. 1. The roll of paper has the guard 10 applied to each annular edge surface thereof with the body portion 10 of each guard sur-- rounding and contacting with the cylindrical surface 11 of the roll and with the corrugated flange 10 extending inwardly and contacting with a radial surface 11 formed by the superimposed edges of the layers of paper. When the band 10 has been applied to the roll 11, the tongue 10 underlies the tongue 10 and the ends of the flange 10 may preferably overlap. A sealing device 12 is then applied to the overlapping tongues 10 and 10 and is operated to effect relative movement of these tongues in a direction adapted to tighten the band or guard around the roll. The stretching device 12 illustrated in Fig. 3 is of the form described and claimed in the co-pending application of Messrs. Chester M. MacChesney, Ralph H. Norton and John Ekern Ott, Serial No. 276,659, filed May 10, 1928, and it comprises a housing 13 having a handle 14 and a base plate 15, which underlies the end of the tongue 10 A gripping dog 16 engages the upper side of the tongue 10 to hold it on the base plate against movement toward the left. as viewed in Fig. 3. A bar 17 is slidably mounted in the housing 13 and carried a head 18 having a part underlying the tongue 10, the free end of which extends in a direction opposite to that of the end of the tongue 10 A gripping dog 19 mounted on the head 18 engages the upper side of the tongue 10 to prevent relative movement thereof with respect to the head 18'toward the right, as viewed in Fig. 3. The bar 17 is provided with rack teeth 17 and the housing 13 contains suitable operating mechanism engaging the rack teeth and operated by a handle 20 so that when the handle 20 is moved upwardly toward the handle 14, the housing 13 and the head 18 are moved away from each other, thereby effecting relative result that the guard or band 10 is tightened around the roll.

When the desired degree of tautness has been obtained in the band 10, the overlapping ends of the tongues 10 and 10 are held in that condition by the stretching device 12, as illustrated in Fig. 3, and there is then applied to the overlapping tongues a suitable seal for securing them in fixed relation to each other. In Fig. 3 of the drawings, there is illustrated a sealing device 21 of the form described and claimed in the co-pending application of Messrs. Chester M. MacChesney and John Ekern Ott, Serial No. 149,307, filed November 19, 1926, comprising a pair of handles 22 which have pivotal connections with a pair of side plates 23 and which operate sealing heads 24 provided with suitable dies for operating upon a channel-shaped seal whereby the walls of the seal are bent into overlapping relation to the tongues and the edges of the seal and the tongues are then bent and partially sheared to provide the form of completed seal described and claimed in the United States patent of Ralph H. Norton No. 1,260,106, dated March 19, 1918. In Fig. 4, the channelshaped seal 25 is shown in position engaging the overlapping tongues 10 and 10 and having the flanges 25 of the seal extending downwardly at the sides of the tongues. Upon applying the sealing device 21 to the sealing blank shown in Fig. 4, and moving the handles 22 thereof inwardly, the walls or sides 25 of the seal are bent inwardly over the ends of the tongues and portions of the edges of the seal and of the tongues are then bent and partially sheared as shown at 26 in Fig. 6. This bending and partial shearing of the seal and the tongues secures the tongues in fixed relation to each other, thus holding the guard or band 10 in tight frictional engagement with the peripheral surface of the paper roll so that it cannot readily be removed therefrom. After the seal 25 has been applied to the tongues to secure them together, the projecting end of the tongue 10 is preferably broken off by bending it back and forth or by cutting it, as shown at 27 in Fig. 6. By means of this invention, a guard or band 10 may be applied to both ends of the cylindrical roll of paper, as shown in Fig. 7, so that the edges of the paper sheets are protected and the band is held in place entirely by its tight frictional engagement with the outer layer of paper so that no fastening means are necessary and injury to the paper is thereby avoided. After the guards or hands 10 have been applied to the paper roll, the

usual outer wrappings of cloth or heavy paper may be applied around the outer surfaces of the roll and of the guards.

Although one form of the invention has been shown and described by way of illusmovement' of the tongues 10 and 10 with the tration, it will be understood that it may be constructed in various other embodiments within the scope of the appended claims.

I claim:

1. The combination with a paper roll, of an annular metallic band engaging the peripheral surface of the roll at the end thereof and havin an annular flange extending inwardly ad acent the end surface of the roll,

said band being provided at one end with a longitudinal slit forming a tongue and having at the other end a projecting tongue similar to said first named tongue, said tongues being superimposed upon each other when said band is applied to the roll, and means engaging said tongues for securing the ends of said band together.

2. The Combination with a paper roll, of an annular metallic band engaging the peripheral surface of the roll at the end thereof and having an annular flange extending inwardly adjacent the end surface of the roll, said band being provided at one end with a longitudinal slit forming a tongue and having at the other end a projecting tongue similar to said first named tongue, said tongues being superimposed upon each other when said band is applied to the roll, and a sealing device enclosing said tongues and having parts forming an interlocking engagement therewith for securing the ends of said band together.
